WebA covalent bond occurs when atoms share electrons. The resulting cluster of atoms is called a molecule, and the compound is considered to be molecular. An ionic bond results from a transfer of one or more electrons from one atom to another. WebAt 15% of the total, the second most massive contribution to galaxy clusters comes in the form of hot plasma — gas where the electrons have been stripped from their atoms — …
WebClusters of atoms smaller than the crit- ical nucleus are called embryos, while those larger than R care called nuclei. Example 7.1 calculates the critical nucleus size and the magnitude of the homogeneous nucleation barrier as a function of the undercooling for pure Al. Example 7.1: Critical radius for nucleation in Al In chemistry, an atom cluster (or simply cluster) is an ensemble of bound atoms or molecules that is intermediate in size between a simple molecule and a nanoparticle; that is, up to a few nanometers (nm) in diameter. The term microcluster may be used for ensembles with up to couple dozen atoms.
